I installed this on
Porsche Cayenne

Review
This gel base product is really amazing. I dilute the the gel with 1 part gel and 3 part water and it is still pretty concentrated. The guy told me can be 4 to 6 part water when I buy. Was worried too much water later no effect. I prepare the mixture and spray on my wheels and rim than went to shampoo the car before washing everything off. Works pretty well except really stubborn ones need abit of rubbing to remove. Overall is a nice to use and smells nice too given the fact that my car is always dirty going in and out of construction sites.

What I like
Nice smell, concentrated, value for money

What I do not like
Could be stronger so that even the most stubborn stain can spray on and wash off with touching it. Just my 2 cent thought.
